Our invention relates to a device for reverse position and extending through the juvenating paint and analogous products housing, one near each end, both ends of said usually put up in air-tight containers and shafts protruding from the housing and the stored on dealers! shelves for retailing purprotruding ends P each adapted to rigidly poses. hold-a paint can holder H.

Opposite movement of the holders (toward each other, above center) is slower and the paint in the cans which is being forced upwardly by the first described motion, will tend to settle or drop, f

the entire oscillatin action setting up a motion of the ingredients which might est be described a movement in the shape of the letter S. The rapid, continued oscillation loosens all sediment or heavier ingredients normally settling in the paint cans and in a short time all the ingredients are mixed thoroughly to a desired usable condition.

With this device therefore a merchant can in a short time and at intervals rejuvenate his entire stock of paint, keeping his stock in the best possible condition for immediate use by the purchasers.

In Fig. 5 a pair of can holders on one side of the device are shown in their respective extreme tilted or oscillated positions. In one oscillating movement the pair of cans move as from the full line to the dotted line positions. It is not compulsory to have the radius bars 22 below center as the device may be equally eflicient with them above center, the main reason for having them in lower position being to have them work in a bath of oil maintained in suitable volume in the housing. The fly-wheel of course func tions as such (to reduce vibration) and it is of course desirable for the same purpose to make the can-holders and other moving parts at each side of the center of corresponding weight.

We have now fully disclosed the preferred construction of our device, its use having been simultaneously fully disclosed. Modi fications may be embodied without departing from the scope and spirit of the invention.

We claim:

1. A portable rejuvenating device for paint and analogous products put up in cylindrical receptacle, said device comprising a mechanism housing, a drive shaft in said housing, and a pair of like rock-shafts parallel to said drive shaft, a receptacle holder on each end of said rock-shaft, means within said mechanism housing for imparting oscillating action to both said rock shafts simultaneously and to oscillate the receptacle holders at each side of the housing in a common plane when the drive shaft is rotated, said receptacle holders on each side 55 arranged to oscillate with an uneven action to agitate the contents of the receptacles as described. a

-2. In a portable paint rejuvenating device comprising an elongated mechanism housing, a drive shaft journaled transversely in the central part thereof, drive means for rotating said shaft, a pair of rock shafts-also journaled therein parallel to the drive shaft one near each end of the housing, paint can holding means fixed to both ends of each said rock shaft exteriorly of the housing: a radial bar fixed in each rock shaftand extending therefrom toward the drive shaft, eccentric cam means for each said bar mounted on the drive shaft and slidably engaging a radius bar to impart oscillatin movement to each said bar and its rock-sha t to oscillate the latter and its can holding means, said oscillating means arranged to impart a rapid oscillating movement to the rock shafts in one direction and a relatively slow movement in the o posite direction.

3. lhe structure speci ed in claim 2, and a fly wheel mounted on the drive shaft intermediate the eccentrics.

In testimony whereof we afiix our signatures.-
